Installing an SDLT or DLTtape

Tape Drive into an HP-UX System

1. Introduction

This document provides instructions for integrating a Quantum®Super DLTtape™ or

DLTtape™ tape drive into an HP®9000 Series 700, 800 System running HP-UX®10.X

or 11.X.

1.1 Purpose and Scope

This document pertains to the following products:

•Tape drives: DLT 2000, DLT 2000XT, DLT 4000, DLT 7000, DLT 8000,

SDLT 220, and SDLT 320. For the DLT 8000, HP-UX permits connectivity on

versions 10.20 and above.

Note: The Super DLT1 tape drive is currently known as the SDLT 220.

•Mini-libraries: DLT 2500, DLT 2500XT, DLT 2700, DLT 2700XT, DLT 4500,

and DLT 4700.

Note: HP-UX will not recognize DLT 2000 series products, but will attempt

to apply generic tape drive parameters. Generic settings are likely to

limit drive performance. These models are not supported with an HP-

UX fbackup/frecover command.

Installing an SDLT or DLTtape Tape Drive into an HP-UX System

4 November 2002 6464118-01

This document includes the following sections:

•“Installation” on page 4 describes how to install an SDLT or DLTtape drive in an

HP9000 system running HP-UX 10.X and 11.X, and how to complete patch

installations.

•“Tape Cartridge Compatibility” on page 9 provides information about SDLT and

DLTtape cartridge and tape drive compatibility.

•“Using a DLTtape Mini-Library” on page 10 provides information about using a

DLTtape mini-library.

2. Installation

This section describes how to install the tape drive and how to configure the HP-UX

operating system to recognize and communicate with the tape drive.

2.1 Before You Begin

Before you install the tape drive, follow these steps:

1. Power down the system.

2. Attach the tape drive to the SCSI interface.

3. Make sure that the hardware has the appropriate SCSI interface for the tape drive. If

you have a SCSI single-ended (SE) tape drive, you need a SCSI SE interface; if you

have a SCSI low-voltage differential (LVD) or high-voltage differential (HVD) tape

drive, you need a SCSI LVD or HVD interface.

4. Obtain the appropriate manual for your tape drive as listed in Table 1. These manuals

provide detailed hardware installation instructions, including switch and jumper

settings and information about SCSI bus termination.

2.2 Installing the Tape Drive

To install the tape drive, follow these steps:

1. Shut down your workstation or server and remove AC power from the system.

2. Follow instructions in your product manual to install the tape drive and set the

SCSI ID.

2.3 Enabling Hardware Compression on the SDLT 320

Tape Drive

To enable hardware compression on the SDLT 320 tape drive, follow these steps:

1. Type ioscan -f to obtain the instance number from the list for your tape drive,

for example, 0[zero].

2. Type mksf -d stape -I <instance #> -b <density code(in decimal)>

-c <compression code(in decimal)>, for example:

mksf -d stape -I 0 -b 147 -c 16

This creates a device file in the format <c#t#d#D###C###>, for example:

c0t14d0D147C16.

IMPORTANT: This device node is created with a rewind at the end of backup.

To create a node with no rewind capability, and with the

Berkley format, type in the following:

n (non-rewind) add -n

b (Berkley) add -u

nb (non-rewind Berkley) add -u -n

The following is an example of a line of code to enable hardware compression on the

SDLT 320 tape drive:

tar -cvf /dev/rmt/ c#t#d#D###C## /name of folder

tar -cvf /dev/rmt/c0t14d0D147C16 /usr

Another example (with no rewind and the Berkley format):

tar -cvf -u -n /dev/rmt/ c#t#d#D###C## /name of folder

2.4 Installing a Patch to the Operating System

Patches allow the operating system to recognize your tape drive and utilize every possible

feature.

Patches can be one of the following two types: tape driver (PHKL) or fbackup/frecover

(PHCO). The tape driver patch is necessary for installation, and the fbackup/frecover

patch is required if you intend to use HP’s fbackup/frecovery utility with your tape drive.

Table 2 specifies the patches for each operating system and hardware.

Note: To download the patches from Hewlett-Packard’s web site, go to

http://www.hp.com/. Because of the nature of HP’s patch database,

patch IDs are subject to change.

To install patches, follow these steps:

1. Download patches from HP.

2. If you haven’t already done so, log in as root.

3. Copy the patches to the /tmp directory.

4. Change the directory to /tmp.

5. Unpack the patch. Be sure to use the appropriate command for your operating system

version. For example:

sh ./<PATCH>

Where <PATCH>is the patch name.

6. Follow the instructions in /tmp/<PATCH>.text.

7. Reboot your system, if necessary.

Installation complete.

Note: After the patches are installed, your system may need the appropriate

tape driver included in the HP-UX kernel. D and K class HP9000/800

systems have a High Speed Connect (HSC) bus included in the

system. If the DLTtape drive is attached through the HSC, then the

stape driver must be included in the kernel. In all other cases, attach

the tape drive through the Native I/O (NIO) bus; this requires the

tape2 driver. Use HP’s SAM utility to install the appropriate driver.

3. Tape Cartridge Compatibility

Table 3 provides information about tape cartridge compatibility. Use this matrix when

determining tape cartridges to use in your tape drive.

Note: The SDLT 220 and SDLT 320 tape drives can read, but not append

data to, DLTtape IV tape cartridges that were previously written by a

DLT 4000, DLT 7000, or DLT 8000 tape drive.

4. Using a DLTtape Mini-Library

HP-UX operating system versions below 10.20 do not support SCSI-2 media changer

device commands. Therefore, you cannot use a DLT 2500, DLT 2500XT, DLT 2700,

DLT 2700XT, DLT 4500, or DLT 4700 in random access mode. You can access the

mini-library in sequential mode only.

Note: At 10.20 and above, you can use the HP-UX mc media changer

commands to operate the mini-library robotics. Refer to HP-UX mc

man page for requirements and usage.

For a detailed description of these access modes, refer to the appropriate product manual

for your DLTtape mini-library. See Table 1 on page 5.
